We regularly run LibreOffice and our extensive test suite through valgrind on Linux, which dungs out -tons- of errors and problems. However - on Windows, we don't get anything like the same level of coverage. If you install 'DrMemory' - http://www.drmemory.org/ (choose to add it in your path works best). Then run: drmemory -- soffice.exe You should get a long slew of uninitialized warnings, and wrong malloc/delete pairings and so on I'll attach a very limited sample of these. You really want to install a pre-compiled Windows build from libreoffice-3-5-1 with debugging symbols: http://dev-builds.libreoffice.org/win32-debug/ Then you can get nice precise stack traces. Then it'd be great to try to hunt down the errors. Unfortunately uninitialized memory errors can be hard to find - they can propagate through the code at great length, and need tracing right back to the first non-initialization. Thanks !
Created attachment 58447 [details] drmemory log a -very- truncated set of results from a run with uninitialized warnings disabled based on the libreoffice-3-5 branch from hash: commit 369aea7f7402e9dc98e9347ae58999dad2d21652 Author: Noel Power <noel.power@novell.com> Date: Thu Mar 1 12:10:56 2012 +0000 fix crash using instances dialog of dataform navigator fdo#44816 ...
We should also (as a 2nd step) work out what is wrong with our GDI usage - which seems to crash/burn drmemory quite severely - I suspect we are busting something in their memory hierarchy somehow.
There are an odd couple of warnings here that need examining too I suppose - peprhas omethreading issue (?) or ... unwinding whatt he errro actually means I guess: ~~Dr.M~~ Error #1: WARNING: GDI usage error: DC 0x40010fdb that contains selected object being deleted ~~Dr.M~~ # 0 system call NtUserCallOneParam.RELEASEDC ~~Dr.M~~ # 1 vcllo.dll!WinSalGraphics::getNativeControlRegion [c:\libo\vcl\win\source\gdi\salnativewidgets-luna.cxx:1416] ~~Dr.M~~ # 2 vcllo.dll!SalGraphics::GetNativeControlRegion [c:\libo\vcl\source\gdi\salgdilayout.cxx:789] ~~Dr.M~~ # 3 vcllo.dll!OutputDevice::GetNativeControlRegion [c:\libo\vcl\source\gdi\outdevnative.cxx:325] ~~Dr.M~~ # 4 vcllo.dll!StatusBar::CalcWindowSizePixel [c:\libo\vcl\source\window\status.cxx:1702] ~~Dr.M~~ # 5 vcllo.dll!StatusBar::ImplInit [c:\libo\vcl\source\window\status.cxx:166] ~~Dr.M~~ # 6 vcllo.dll!StatusBar::StatusBar [c:\libo\vcl\source\window\status.cxx:174] ~~Dr.M~~ # 7 fwklo.dll!framework::LayoutManager::implts_createProgressBar [c:\libo\framework\source\layoutmanager\layoutmanager.cxx:918] ~~Dr.M~~ # 8 fwklo.dll!framework::LayoutManager::createElement [c:\libo\framework\source\layoutmanager\layoutmanager.cxx:1555] ~~Dr.M~~ # 9 fwklo.dll!framework::StatusIndicatorFactory::impl_createProgress [c:\libo\framework\source\helper\statusindicatorfactory.cxx:479] ~~Dr.M~~ #10 fwklo.dll!framework::StatusIndicatorFactory::initialize [c:\libo\framework\source\helper\statusindicatorfactory.cxx:144] ~~Dr.M~~ #11 fwklo.dll!framework::Frame::initialize [c:\libo\framework\source\services\frame.cxx:610] ~~Dr.M~~ Note: @0:04:26.648 in thread 3896 ~~Dr.M~~ ~~Dr.M~~ Error #2: WARNING: GDI usage error: deleting an object 0x9f0a0b5a that is selected into DC ~~Dr.M~~ # 0 system call NtGdiDeleteObjectApp ~~Dr.M~~ # 1 vcllo.dll!WinSalGraphics::SetFont [c:\libo\vcl\win\source\gdi\salgdi3.cxx:1691] ~~Dr.M~~ # 2 vcllo.dll!OutputDevice::ImplReleaseGraphics [c:\libo\vcl\source\gdi\outdev.cxx:739] ~~Dr.M~~ # 3 vcllo.dll!Window::~Window [c:\libo\vcl\source\window\window.cxx:4538] ~~Dr.M~~ # 4 vcllo.dll!DockingWindow::~DockingWindow [c:\libo\vcl\source\window\dockwin.cxx:482] ~~Dr.M~~ # 5 vcllo.dll!ToolBox::~ToolBox [c:\libo\vcl\source\window\toolbox.cxx:1815] ~~Dr.M~~ # 6 vcllo.dll!DecoToolBox::calcMinSize [c:\libo\vcl\source\window\menu.cxx:620] ~~Dr.M~~ # 7 vcllo.dll!DecoToolBox::DecoToolBox [c:\libo\vcl\source\window\menu.cxx:576] ~~Dr.M~~ # 8 vcllo.dll!MenuBarWindow::MenuBarWindow [c:\libo\vcl\source\window\menu.cxx:5179] ~~Dr.M~~ # 9 vcllo.dll!MenuBar::ImplCreate [c:\libo\vcl\source\window\menu.cxx:3352] ~~Dr.M~~ #10 vcllo.dll!SystemWindow::SetMenuBar [c:\libo\vcl\source\window\syswin.cxx:957] ~~Dr.M~~ #11 fwklo.dll!framework::LayoutManager::createElement [c:\libo\framework\source\layoutmanager\layoutmanager.cxx:1535] ~~Dr.M~~ Note: @0:09:26.966 in thread 3896 running with -ignore-asserts -no_check_gdi gets past this into other erors though - perhaps it's just a big in drmemory's gdi checking code :-)
